IHME works closely with the Inter-American Development Bank (IDB) to collect and analyze data to evaluate the impact of the Salud Mesoamérica Initiative (SMI), a results-based aid project seeking to reduce inequalities in maternal and child health across Mesoamerica. IHME advises on the selection of performance indicators and performance targets, supports in study design, survey development and implementation, verifies and analyzes data, and disseminates results. IHME has completed baseline and first follow-up evaluations in SMI’s eight participating countries (El Salvador, Mexico, Honduras, Nicaragua, Panama, Guatemala, Belize, and Costa Rica), including the capture of over 90,000 censuses, over 20,000 household surveys, and over 900 health facility surveys. IHME continues to disseminate findings from the baseline and first follow-up evaluations through the production of indicator summary and data quality reports, presentations, and scientific publications. A second follow-up evaluation is under way, to be carried out through late 2018.
